The GSD 25 premium sonar module is a remote network solution that provides exceptional fish tracing and background tracing capabilities. It features 1-channel, 1-kW CHIRP plus Garmin's CHIRP DownVü and SideVü scan sonar to enjoy the sharpest scan images in the water. The images sent to the compatible Garmin chartplotter provide such clear and precise target details that you can distinguish between small and very close fish at key depths of up to 1,52 kilometers (5,000 feet).


CHIRP of 1 kW real of two channels

CHIRP is the most sophisticated sonar technology available to users in the field of fishing and navigation. CHIRP is the acronym for Compressed High-Intensity Radiated Pulse. What you will get is a resolution, clarity and clarity of the objectives much higher than with any other sonar system. If you have the Garmin 2-channel real 1 kW CHIRP probe as your usual sonar, you can adjust CHIRP frequencies in low / medium, low / high and medium / high to optimize sonar performance. The transducer is sold separately.

Scan sonar provide the sharpest images in water

By incorporating CHIRP technology into DownVü and SideVü scan sonars, higher resolution, better target spacing and sharper images of structures and fish passing underneath and on the sides of the boat are achieved. . Integrated in our new combinations GPSMAP xsv and in the GSD 25 premium sonar module, it uses a transducer for the traditional CHIRP HD-ID sonar and the CHIRP DownVü and SideVü scan sonar. The transducer is sold separately.
